May 24, the news (special author Du Jianmin) has gone through morethan ten years from the concept to the pilot test to the comingfull implementation. In these more than ten years, who is thebiggest beneficiary of the number-carrying transfer network, whichis not only a topic of great concern to operators, but also a hotspot for all kinds of curious people to rest assured. So what arethe factors that affect the user bring-in and take-out, and who isthe real biggest beneficiary in the end?

I. What are the key factors affecting user portability

To be frank, all three operators have users who can't standthemselves and want to bring them out. For those users who tend toswitch or leave the network, the operators'operational earlywarning system also has a general forecast. What factors affect theuser's choice of entry?

Network experience may be the primary consideration. Whether it isthrough mobile phones or telephone calls, or through fixed-linebroadband Internet access, these have become just the needs ofusers. If the resident's network signal is poor or the networkexperience is poor, and this situation can not be improved for along time, then the user's network transfer will be a probableevent. In terms of network, the number of 4G base stations and thewide coverage of fixed network home, China Mobile is undoubtedlythe largest and widest industry.

Transparent consumption is essential. Now the national level hasbeen promoting the governance of "customization without knowledge".The reason why "uninformed customization" has risen to the nationallevel, of course, reflects the seriousness of the problem, but alsoreflects the operator's inaction or slow action to rectify thework, or even indulge or tolerate the spread of "uninformedcustomization". In fact, from the user's point of view, this is nodifferent from robbery or theft.

The of complaint service determines the final choice ofusers. If there are problems, whether the operator is in charge ornot; if the operator is in charge, whether it can be solvedeventually, these ultimately determine whether the users who havethe tendency to switch to the network will stay or not, and alsodetermine the number of users brought in. Although operators haverepeatedly emphasized user demand-oriented, but in the specificbusiness process, this orientation also needs to be furtherreflected in the of service.

2. What is the user mobility rate brought about by thenumber-carrying network transfer?

If we compare the number of users who transact the service with thetotal user data at that time, we can conclude that the businesstransactional rates as of June 2016 and December 2018 are about0.32% and 0.98%, respectively. Is the inter-network mobility ratesuch as users high or low?

The situation in Hong Kong and Taiwan may serve as a reference forus. It is reported that in Hong Kong, China, since 1999, theproportion of number carriers per year has dropped from the initial15% to the present 4%. In Taiwan, the total number of mobilesubscribers in 2017 is 28.78 million, the number-carrying transfernetwork among users is about 3 million, and the annual activity ofthe transfer network is 10%. The users in Hong Kong and Taiwan aregenerally small in size, and how much they can use for reference isstill not well appreciated.

China Institute of Information and Communications has predicted thenumber-carrying data of China. The total number of mobile users is1.55 billion. The annual activity of network-switching during thepilot period is 0.3%-0.5%, and the number of users ofnetwork-switching is between 4.65 million and 7.75 millionannually.

Whether it is 0.32% or 0.98% in the pilot provinces, or 4% or 10%in Hong Kong and Taiwan, or 0.3% to 0.5% predicted by the ChinaInstitute of Communications and Communications, the participationof the number-carrying network is not as much as it shows whenparticipating in hot discussions on the Internet.

3. The situation of pilot provinces and cities shows that ChinaTelecom seems to win.

We learned from the regular briefing of the State Council's policyheld by the Information Office of the State Council on May 21 thatthe Ministry of Industry and Information Technology has organizedrelevant enterprises to carry out experiments in five provinces andmunicipalities. At present, nearly 2 million people have completedthe work of carrying numbers to transfer networks.

According to the latest data from open channels, as of the end ofDecember 2018, 167,000 people had been transferred to the networkwith numbers. Of particular concern is the addition of 630,000people in 2018, an increase of 62% over the previous year. Lastyear, the simple process of new launch was very popular with users.After the launch of the new process, the number of carriers hasrisen sharply, and reached the peak of monthly carriers in December2018.

At present, we have not yet the latest data from openchannels to the user's carrying in and out among the three majoroperators. However, the past data also deserve our attention, andthe historical data of China Telecom has shown that the number ofusers brought in by China Telecom is relatively leading.

According to the data from the Ministry of Industry and InformationTechnology, by the end of June 2016, more than 450,000 users infive provinces (municipalities) had handled the number-carryingbusiness. Among them, China Telecom brought in 168,000, brought out66,000; China Mobile brought in 162,000, brought out 250,000; ChinaUnicom brought in 147,000, brought out 161,000.

Past data show that, in terms of scale, China Telecom has thelargest number of users, while China Mobile has the highest numberof users; China Unicom has the highest rate of users. This is alsovery understandable, China Mobile has the largest number of users,and only from a probability point of view, China Mobile should alsohave the largest number of potential users. Therefore, the finalinvestigation of the situation of bringing in and bringing out, orfrom a variety of ratios to analyze.

Fourth, the majority of users are the biggest beneficiaries of thenumber-carrying network

It is very clear to tell you that the biggest beneficiaries ofcarrying number to transfer network are not any of the three majoroperators. Even if a certain operator may bring in more users, eventhe ratio of user's carrying amount to carrying amount is thelargest. In fact, the biggest beneficiaries of carrying numbers tothe network are the vast number of users. With the people as thecenter, the concept of "carrying numbers to transfer networks" isto develop the network with people as the center.
